ATI Pediatrics Exam 4 | Nurselytic

Correct Answer: A

Rationale: The correct answer is A. Surgical repair for PDA prevents increased pulmonary vascular congestion. PDA is a condition where the ductus arteriosus, a blood vessel that connects the pulmonary artery to the aorta in fetal circulation, remains open after birth. This leads to increased blood flow to the lungs, causing pulmonary congestion. By surgically closing the PDA, we reduce the volume of blood flowing to the lungs, thus preventing pulmonary vascular congestion.

Choices B, C, and D are incorrect because surgical repair of PDA does not directly address these issues.
Choice B is incorrect because PDA closure does not specifically reduce the workload on the left side of the heart.
Choice C is incorrect because PDA repair does not prevent pulmonary infections.
Choice D is incorrect because PDA closure eliminates the right-to-left shunt of blood, not causes it.
